Created on 29 May 2020 · 11Comments · Source: berstend/puppeteer-extra

StealthPlugin fails with TypeError after upgrade to puppeteer v3.2.0.

TypeError: browser.setMaxListeners is not a function
    at StealthPlugin.onBrowser (.../node_modules/puppeteer-extra-plugin-stealth/index.js:155:13)
    at StealthPlugin._bindBrowserEvents (.../node_modules/puppeteer-extra-plugin/dist/index.cjs.js:479:24)

Note, according to release notes, puppeteer v3.2.0 switched to Mitt instead of EventEmitter.

Workaround:

const puppeteer = require('puppeteer-extra');
const stealth = require('puppeteer-extra-plugin-stealth')();

stealth.onBrowser = () => {};
puppeteer.use(stealth);

Workaround:

const puppeteer = require('puppeteer-extra');
const stealth = require('puppeteer-extra-plugin-stealth')();

stealth.onBrowser = () => {};
puppeteer.use(stealth);

@bacaist yep, I know you can pin the last good known version.

However, if you want to be up to date with upstream dependency (which is updated often), you can apply above workaround (consider to have a look at source code of Mitt and StealthPlugin to better understand the change).

@akornatskyy any idea how to implement that fix in typescript? That doesn't seem to work for me as shown in your solution.
